Free-space optics (FSO) is a line-of-sight technology that uses lasers to provide optical bandwidth connections that can send and receive voice, video, and data information on invisible beams of light.

TOP500 SUPERCOMPUTER SITES The TOP500 project was started in 1993 to provide a reliable basis for tracking and detecting trends in high-performance computing. Twice a year, a list of the sites operating the 500 most powerful computer systems is assembled and released. The best performance on the Linpack benchmark is used as performance measure for ranking the computer systems. The list contains a variety of information including the system specifications and its major application areas.

BRIEF OVER VIEW OF FIBER OPTIC CABLE ADVANTAGES OVER COPPER: • SPEED: Fiber optic networks operate at high speeds - up into the gigabits • BANDWIDTH: large carrying capacity • DISTANCE: Signals can be transmitted further without needing to be "refreshed" or strengthened. • RESISTANCE: Greater resistance to electromagnetic noise such as radios, motors or other nearby cables. • MAINTENANCE: Fiber optic cables costs much less to maintain.

Fiber Dispersion Once upon a time, the world assumed that fiber possessed infinite bandwidth and would meet mankind’s communication needs into the foreseeable future. As the need arose to send information over longer and longer distances, the fiber optic community developed additional wavelength “windows” that allowed longer transmission. The 1550 nm region, with a loss of only 0.2 dB/km, seemed like the answer. Millions of kilometers of fiber were installed around the world creating a high-speed communication network. However, as the data rates increased and fiber lengths increased, limitations due to dispersion in the fiber became impossible to avoid.

We terminate fiber optic cable two ways - with connectors that can mate two fibers to create a temporary joint and/or connect the fiber to a piece of network gear or with splices which create a permanent joint between the two fibers. These terminations must be of the right style, installed in a manner that makes them have little light loss and protected against dirt or damage in use. No area of fiber optics has been given greater attention than termination. Manufacturers have come up with over 80 styles of connectors and and about a dozen ways to install them. There are two types of splices and many ways of implementing the splice. Fortunately for me and you, only a few types are used most applications.

What is fiber optics? Picture sending signals zipping along from one location to another in the form of light guided through thin fibers of glass or plastic. These signals can be analog or digital - voice, data or video information and fiber can transport more information longer distances in less time than any copper wire.

The Basics of Fiber Optic Getting Started in Fiber Optics - You need tools, test equipment and - most of all - training!
This guide will help you get started by providing very basic information (we will also point you to more advanced studies) and demonstrating that you don't need to break the bank to break into the field.
What is "Fiber Optics"? And a short history.

Optical Fiber
Fiber Specifications
The usual fiber specifications you will see are size, attenuation and bandwidth. While manufacturers have other specs that concern them, like numerical aperture (the acceptance angle of light into the fiber), ovality (how round the fiber is), concentricity of the core and cladding, etc., these specs do not affect you.

Choosing a cable - what hazards will it face? Cable's job is to protect the fibers from the hazards encountered in an installation. Will the cables be exposed to chemicals or have to withstand a wide temperature range? What about being gnawed on by a woodchuck or prairie dog? Inside buildings, cables don't have to be so strong to protect the fibers, but they have to meet all fire code provisions. Outside the building, it depends on whether the cable is buried directly, pulled in conduit, strung aerially or whatever. You should contact several cable manufacturers (two minimum, three preferred) and give them the specs. They will want to know where the cable is going, how many fibers you need and what kind (singlemode or multimode or both in what we call "hybrid" cables.) You can also have a "composite" cable that includes copper conductors for signals or power. The cable companies will evaluate your requirements and make suggestions. Then you can get competitive bids.

Fiber Optic Network In the telcos, singlemode fiber is used to connect long distance switches, central offices and SLCs (subscriber loop carriers, small switches in pedestals in subdivisions or office parks or in the basement of a larger building). Practically every telco's network is now fiber optics except the connection to the home. Fiber to the home is not yet cost effective - especially since most homes do not want (nor are willing to pay) for the high speed services that would justify fiber optics.

Estimating and Bidding Estimating is necessary to figure out what the job will cost you. First of all you'll need to set up a simple chart of all the details: the items you will need to purchase (i.e. cable, connectors, etc) and their costs. You will also need to add labor cost.
Do your homework - be sure to have an accurate idea of how long it takes for each step of the installation .

Fiber Optic Testing After the cables are installed and terminated, it's time for testing. For every fiber optic cable plant, you will need to test for continuity, end-to-end loss and then troubleshoot the problems. If it's a long outside plant cable with intermediate splices, you will probably want to verify the individual splices with an OTDR also, since that's the only way to make sure that each one is good. If you are the network user, you will also be interested in testing power, as power is the measurement that tells you whether the system is operating properly.
You'll need a few special tools and instruments to test fiber optics.
